For a few years, one of particle physics’ most unsettling numbers seemed to be pointing somewhere strange. The trouble ...

The new calculation, made at the Large Hadron Collider (LHC) near Geneva, could help solve a niggling mystery about this ...

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, ...

The study succeeded in explaining the discrepancy, but to understand it we need to take a few steps back and start again with a somewhat more detailed description of the muon. The muon is a particle ...

Physicists at multiple institutions are compressing particle accelerators from facility-scale machines stretching hundreds of ...

CHICAGO (CBS) -- A powerful new particle accelerator that could be set up at Fermilab, a telescope to observe the oldest light in the universe, and research to learn more about mysteries such as dark ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

The Theoretical Advanced Study Institute in Elementary Particle Physics (TASI) recently concluded its 40th year, bringing 65 students from around the world to Boulder to delve into the “Frontiers of ...

There are many outstanding questions about the universe: What is the nature of dark matter? Why is the universe expanding? How do neutrinos acquire their mass? Because experiments to answer these ...

A new study suggests that faint, ancient ripples in spacetime may hold the key to one of physics’ greatest mysteries.
